摘要： 为解决特殊应用场景下智能视频监控系统存在的监测范围有限、监控资源分配不合理、运动目标发现不及时等问题,利用雷达探测电磁波穿透能力强、搜索范围大、不受特殊气候及光学条件影响的特点,结合无人机和自动导航小车的灵活性和机动性,提出了一种雷达指引的综合联动视频监控方法,并在此基础上研究了一种基于大地坐标的统一坐标定位体系以及使用粒子群优化算法进行优化的基于模糊神经网络的运动目标智能分配定位算法。该算法根据雷达探测信号可自动计算出每台摄像机在水平、垂直和变焦3个维度上的控制参数,结合联动控制系统实现运动目标的实时定位和追踪。通过对某文物保护现场的实地测试,大地坐标定位体系的目标定位精度达到了99.84%,基于模糊神经网络的运动目标智能分配算法的准确率达到了95%,能够实现目标的精准定位和监控资源的智能分配,具有较高的实际应用价值。
